BUSH-HAMMER.

SPECIFICATION forming part of Letters Patent No. 470,570, dated March 8,1892. Application filed July 30, 1891. Serial No. 401,182 (No model.)

To all whom it may concern: 0

Be it known that I, CLARK HOLDEN of Barre,

in the county of Washington andState of Vermont, have invented anew andImproved Bush-Hammer, of which the following is a full, clear, and exactdescription.

The object of tlie'invention is to provide a new and improvedbush-hammer which is simple and durable in construction, securely holdsthe blades in position, and permits of conveniently separating theseveral parts to take out the blades for sharpening or other purposes.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter described, and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar. letters of reference indicatecorresponding parts in allthe figures.

Figure 1 is a perspective view of the iniproveinent. Fig. 2 is asectional side elevation of the same on theline 2 2 of Fig. 3. Fig.

3 is a sectional plan view of the same on the line 3 3 of Fig. 2, andFig. 4 is a perspective view of one of the gibs. I

The improved bush-hammer is provided with thetwo body-plates A and A,arranged opposite each other and formed at their inner sides at themiddle with bosses B and B, respectively, having a groove extendingtransversely to form an eye 0 for the handle of the hammer. At the endsof the bossesB and B are arranged the transversely-extending gibs D andD, provided at their middle with inwardly-extending ton gues-D and Drespectively, fitting into a corresponding V-shaped groove E, arrangedlongitudinally in the adjacent faces of the bosses B and B. Bolts F andFpass through the body-platesAAaud the tongues D D to securely hold theplates and gibs in position. Opposite the tongues D a'nd D are arrangedgrooves D and D respectively, in the gibs D and D, respectively, thesaid grooves being engaged by tongues G G formed on the inner ends ofthe sets of cutting-blades G G, held between the outer ends of thebody-plates A A.

In order to fasten the cutting-blades G G, sets of bolts H H,respectively, are employed, passing'through the bod y-plates A A and thesaid sets of cutting-blades, as plainly illustrated in the drawings. Itwill be seen that by this arrangement the gibs D D are securely held inplace between the body-plates A A, as all lateral motion is prevented bythe tongues D D engaging the longitudinal slot E in the bosses'B B. Alike motion of the sets of cutting-blades G G is prevented by the saidcutting-blades engaging with their tongues G G the grooves D D in thegibs D D.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. A bush-hammer comprising oppositelyarrangedbody-plates having central bosses and transverse. gibs fitted betweenthe said plates on the ends of the bosses, each gib being provided witha tongue fitting into a lon itudinal roove formed in the said bosses,

and bolts passing through the said bodyplates and through the said gibsto hold the body-plates and gibs in position, substantially as shown anddescribed. i

2. A bush-hammer comprising oppositelyarranged body-plates havingcentral bosses and transverse gibs. fitted between the said plates onthe ends of the bosses, each gib being provided with a tongue fittinginto alongitudinal groove formed in the said bosses,

sets of cutting-blades formed with tongues engaging grooves in the saidgibs, and bolts for fastening the said gibs to the said bodyplates, andbolts for fastening the sets of blades between the body-plates,substantially as shown and'described.
